Description
Technical Field
The invention relates to the technical field of engines, in particular to a water jacket runner structure, a temperature control method and an engine.
Background
The cooling system of an automotive engine is one of the most important systems of the engine and functions to maintain the engine within a proper temperature range under all operating conditions. The cooling system is intended to prevent overheating of the engine and also to avoid overcooling of the engine during cold winter. After the engine is cold started, the cooling system also ensures that the engine is quickly warmed up to reach the normal working temperature as soon as possible.
The cooling system is divided into water cooling and air cooling, wherein the water cooling is adopted by most of automobiles on the market due to the advantages of high heat dissipation rate, uniform cooling, reliable operation, low noise and the like, and is not easily affected by the environment. In the cooling system, the water jacket is used for transmitting the temperature of the combustion chamber of the engine and the temperature of the inner wall of the cylinder body into cooling liquid in a heat conduction mode, and the cooling liquid flows through a thermostat, a radiator and the like under the action of a water pump, so that the whole cooling cycle is completed. It follows that the water jacket plays a critical role in the overall cooling system, and its efficiency in transferring the temperature of the combustion chamber and cylinder inner wall into the coolant will directly affect the efficiency of the overall cooling system, and thus the reliability and durability of the engine as a whole.
The traditional water jacket mainly comprises a cylinder cover water jacket and a machine body water jacket. After being pressurized in the water pump, the cooling liquid enters the engine body water jacket of the engine through the water diversion pipe. The cooling liquid flows around the water jacket wall, absorbs heat from the water jacket wall, heats up and flows into the water jacket of the cylinder cover, absorbs heat from the water jacket wall of the cylinder cover, and flows into the radiator through the thermostat and the radiator water inlet hose. In the radiator, the cooling liquid radiates heat to the air flowing around the radiator to cool, and finally the cooling liquid returns to the water pump through the radiator water outlet hose to circulate. Obviously, the heat exchange capability of the traditional water jacket structure cannot be enhanced when the cooling liquid flows, the cooling liquid cannot be rapidly lifted to the normal working temperature when the temperature of the cooling liquid is low, and the cooling liquid cannot be rapidly cooled even if the temperature of the cooling liquid is high by simply relying on a radiator.
Therefore, a water jacket runner structure, a temperature control method, and an engine are required to solve the above-described problems.
